An interest in the possible correlation between BIID and RLS

I've been thinking about this and it's been haunting me for a while. I learned about BIID only a slight bit ago, and now I've been thinking about the correlation with RLS, Restless Legs Syndrome. I haven't done any studies, but I'm quite interested in perhaps doing one. I've always had symptoms similar to BIID, particularly in my right leg. I also have RLS, especially in my right leg as well. I wonder if perhaps they could be connected in some way, maybe it could be a similar mutation in the brain? I'm very intrigued about this, because it would open up some more information on both disorders.
